The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is done concrete introduction.
Fig. 1 is the perspective view of a preferred embodiment of the seamless bonding machine that is applicable to the panel beating thin plate of the present invention; Fig. 2 is the schematic process flow diagram that is applicable to the seamless welding method of panel beating thin plate of the present invention; Fig. 3 utilizes the seamless bonding machine of panel beating thin plate and the seamless welding method of being applicable to of the present invention to carry out the Fundamentals of Welding schematic diagram.
Figure 1 shows that a preferred embodiment that is applicable to the seamless bonding machine of panel beating thin plate of the present invention, mainly comprise: welding main body 1, welding top electrode 2, welding bottom electrode 3.
As shown in Figure 1, welding top electrode 2 is connected with above-mentioned welding main body 1 with welding bottom electrode 3, is dismountable between welding top electrode 2, welding bottom electrode 3 and the welding main body 1; Welding top electrode 2 is positioned at the top of welding bottom electrode 3, its lower end is formed with upward welding plane A down, the upper end of welding bottom electrode is formed with following welding plane B up, be parallel to each other between last welding plane A and the following welding plane B, it should be noted that herein, last welding plane A and following welding plane B should have certain area, so that the even distribution of heat and suitably dispersive pressure.
As a kind of preferred version, the area of following welding plane B is greater than the area of last welding plane A.
As a kind of preferred version, welding top electrode 2 is block electrode, and welding bottom electrode 3 is tabular electrode.As shown in fig. 1, the electrode of described bulk is meant that the wide and high size of the coffin of the minimum that electrode is shared is more or less the same; And welding bottom electrode 3 is tabular electrode, and described tabular electrode is meant that the length and the wide size of comparing of the coffin of the minimum that electrode is shared are more or less the same, and length and width is compared with height, and high size is much smaller relatively.As shown in Figure 1, as preferably, welding top electrode 2 is that rectangular cross section is trapezoidal for a lower surface, and welding bottom electrode 3 is a rectangular slab.
